ATTACH IV! Eur FD R CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 378,569, dated February 28, 1888.

Application filed September 20, 1887. Serial No. 250,180. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM H. BOWMAN, of South Solon, in the county of Madison and State of Ohio, have invented a new and 1m proved Attachment for Gorn l?lanters,of which the following is a full, clear, and exact description.

My invention relates to a check attachment for corn-planters, and has for its object to provide a means whereby a reliable check may be attached to any style of cornplanter, and wherein the said attachment may also be used for drilling the corn; and the further object of the invention is to provide a means whereby in irregularly-shaped fields the checking may be accomplished as regularly as in rectangular fields.

The further object of the invention is to construct a reliable check -row attachment which will be cheap in construction and reliable and effective in operation.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarletters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the attachment secured to a corn-planter, and Fig. 2 is a transverse section on line 00 0c of Fig. 1. Fig. 3 is a side elevation of the attachment, and Fig. 4: is a plan view of the clearance and regulating bar. Fig. 5 illustrates a modification of the adjusting-bar; and Fig. 6 is a detail view of the marker,illustratin g the application thereto of an adjustable gage.

In carrying out the invention the body of the attachment consists of a beam, A, the forward end of which is recessed at each side to a point at the rear of the center to form the tongue or reduced portion A.

In the beam, transversely to the same and to the rear of the tongue, a shaft, a, is jour naled, carrying at each end a marking-bar, B, which bars or markers are secured centrally to the shaft a, turning therewith, having their extremities pointed and preferably curved in opposite directions. The markers may, however, be made straight, as shown in Figs. 5 and 6, without departing from the spirit of my invention.

Upon the inner side of each marker, near opposite ends, pins b are attached, and the 'beam A, at the rear of the shaft, is provided with aligning recesses b in the opposing edge, through which the pins 12 pass when the markers, which are secured parallel upon the shaft, are revolved.

A short bar, B, is made to project centrally from each edge of the markers at right angles thereto, the said bar being preferably in one piece, whereby substantially the shape of an X is imparted to the markers, having one leg shorter than the other. The purpose of the bar B is to afford a grip for the hand, so that in the event the markers are thrown out of check from any cause they may be turned and placed in registry again.

A bar, 0, is attached transversely the rear upper end of the body-beam A. Extending out from each side edge and upon the bar 0 scraper-blocks O are adjustably secured by bolts or otherwise to project forward in alignment with the axis of the markers. Each of the scraper-blocks is provided with a V-shaped recess or slot, in its forward end, through which recess the ends of the markers are adapted to pass, as illustrated in Fig. 1.

At each side of the tongue A, about centrally the same, levers D and D are respectively pivoted by one pivotal pin, (1, passing through the tongue and levers. Both. ends of the levers are unattached, the rear ends extending nearly to the shoulder produced in the body-beam by the side recesses forming the tongue, at which point the levers are alternately acted upon by the pins 1:, secured to the markers, for a purpose hereinafter specified.

The forward ends of the levers are adapted to bear'against the under face of thelongitudinal members 6 e of an inverted-T-shaped rocking bar, E, pivoted in bearings 6 slightly above the tongue, centrally the lower end. The under face of the rocking bar is convened, and the upper end of the vertical member is provided with a series ofapertures, f, in one of which apertures a link, F, is secured, the other end of said link being adapted for attachment to the sliding bar of the seed-boxes of a corn-planter, to reciprocate the same.

The attachment is preferably attached to a planter through the medium of a beam, F, at tached at right angles to the forward end of the tongue, the said beam being detacha'bly 2 erases secured to the body of the planter in any approved manner.

Beneath the tongue A, near the forward end, a drag, H, is pivoted, consisting of a body, h, adapted to rest upon the ground, provided with a vertical beveled projection, h, integral with its forward end, upon the outer beveled face of which projection fenders II are secured, constructed of metal plates placed at an angle to each other, having their contiguous edges united to cover the outer pointed edge of the projection h, and their outer faces made concave or curved inward centrally and outward at the projecting ends. Upon the upper surface of the body h a lug, 7c, is cast or otherwise formed, provided with a setscrew, k, in its upper end, and the body is pivoted to the tongue by an upwardly-inclined arm, K, integral with and extending outward from the projection h, as illustrated in Fig. 8.

The object of the drag is twofold. By means of the set-screw is, upon which the body-beam A rests, the said beam may be vertically adusted, and the depth that the markers shall penetrate the ground be thereby regulated. The drag, also, by means of the levelers, clears and smoothes the ground in advance of the markers. If found desirable, the set -screw upon the drag may be dispensed with, and the adjustment of the markers be effected by adjustably attaching a bar, M, to the rear of the planter, as shown in Fig. 5, which bar is made to pass beneath the body-beam A and engage its under surface. To prevent the markers from sinking too deep, a series of apertures, 172, may be made longitudinally at each end, and pointed centrallyapertured slats M are transversely attached to the markers a suitable distance from their ends, through the medium of the apertures m and bolts or other suitable adjustable fastening devices, as shown in Fig. 6.

In operation, as the planter having the attachment secured thereto is driven along the markers B revolve, and the pins 0, acting upon the levers D and D, alternately depress their rear ends, causing their forward ends to raise either the member 0 or e of the rocking bar E, which, through the link-connection aforesaid, reciprocates the drop-bar of the planter and causes the seed to flow down into the drill simultaneously with each check.

It will be observed that should the wheel of the planter slip forward or backward, or run over clods of hard dirt, the deviation will not have any effect upon the markers, and that should the'marking-wheel get out of check it only becomes necessary to slightly raise the beam A and turn the wheel back or forth to register with the mark last made.

In irregularly-shaped fields when the irregularities are reached the attachment is unhooked Letters Patent, is

1. The ground-markin g attachment for cornplanters, wherein the marker proper consists of a single centrally-hung revolving bar which acts upon the ground at its ends, marking it at intervals, substantially as set forth.

2. In a ground-marking attachment for cornplanters, the marker proper consisting of a single centrally-hung revolving bar having its ends pointed and curved in opposite directions, substantially as specified.

8. In a ground-marking attachmentfor cornplanters, the centrally-hung revolving marking-bar provided with pins or projections near relatively-opposite ends andhaving their ends adapted to more or less enter and mark the ground, in combination with actuating-levers hung upon the bar carrying the said marking-bars, and which levers operate the corndropping-slideactuating mechanism, substantially as set forth.

4. In an attachment for corn-planters, the combination, with the bar adapted to be applied to the frame of the planter and carrying side levers actuating the corn-dropping-slideactuating mechanism, of the groundmarkers supported upon said bar and provided with adjusting-apertures to receive stops to regulate the depth of penetration of the arms of the markers, substantially as set forth.

5. The combination, with the bar carried by the corn-planter frame and carrying side levers actuating the corn-slide-operating mechanism, and markers provided with pins acting upon said levers, of the drag-bar pivoted or connected to the aforesaid bar and carrying a IIO supporting and adjusting screw, substantially as set forth.

6. 'Ihe combination, with the bar adapted to be applied to the planter-frame and carrying side levers actuating the corn-slide-actuating mechanism and operated upon by pins projecting from markers, of a supporting and adjusting bracket, substantially as specified.

7 The combination, with the bar adapted to be applied to the frame of the planter and carrying side levers actuating thecorn-slide-opcrating mechanism, and the markers acting upon said levers, of the bifurcated scrapers adjustable upon the said planter-frame and adapted to receive the markers, substantially as set forth.
